Water cycling cultivating device for fish and vegetables commensalism and water cycling cultivating method

Abstract

The invention discloses a water cycling cultivating device for fish and vegetables commensalism and a water cycling cultivating method. The device includes a microbial decomposition filter tank, a plant cultivation pond, an aquatic animal breeding pond, a water cycling system, a biological filler, a light-supplementing system and a water pump, wherein the aquatic animal breeding pond is positioned at the lowermost end of the device; the plant cultivation pond is arranged at the middle part of the device; the microbial decomposition filter tank is positioned at the uppermost of the device; the microbial decomposition filter tank, the plant cultivation pond and the aquatic animal breeding pond are connected with one another in a two-by-two manner through the water cycling system; the water body in the system flows from the aquatic animal breeding pond to the microbial decomposition filter tank and the plant cultivation pond successively, and then flows back to the aquatic animal breeding pond. Compared with the conventional cultivation method, the device provided by the invention has the advantages that the growth cycle of the plant cultivated in the device is shortened by 10-20%, the irrigation water is saved by 90%, and the agricultural land is saved by 50%.

Description

Technical field [0001] The present invention is a field of plant planting and aquaculture technology, involving the combination of plant planting and aquaculture technology with unified high -efficiency breeding devices.More specifically, it is a kind of fish and vegetable symbiosis recycling cultivation planting device and method. Background technique [0002] At present, my country's agricultural production model is relatively single. Land planting technology and aquaculture technology are used as different fields and are applied to different agricultural industries.However, different production models are limited by conditions in many natural environments such as air, temperature, soil, and water body, which leads to the geographical location of agricultural production away from living areas, and the efficiency of production technology and economic conversion continues to decrease.In addition, a single production model needs to add many human factors due to the instability of ...

AI Technical Summary

Problems solved by technology

However, different production modes are restricted by many natural environments such as air, temperature, soil, water, etc., which leads to the geographical location of agricultural production far away from the living area, while the production process and economic transformation efficiency continue to decrease

In addition, the single production mode needs to add many human factors due to the instability of the ecosystem

The addition of various fertilizers, pesticides, and chemicals leads to a decline in product quality and an increase in production costs
